This volume Biology in Waldorf Schools by Dirk Rohde has been translated and adapted from the Handbook for Upper Grades in Waldorf Schools, which was published in German by Beltz Juventa in 2018. In this work, edited by Stephan Sigler, Wilfried Sommer and M. Michael Zech, those subjects given in the format of block-lessons are examined with respect to educational theory and didactical and methodological aspects. The publication is intended for scientists, students and practicing teachers. It emerged from a research project by the Pedagogical Research Centre at the Federation of Waldorf Schools in Kassel and the Alanus University of Arts and Social Sciences in Alfter.
